Alsa problems after a system upgrade

Hi there,

Re: Alsa problems after a system upgrade

Have you tried alsamixer -c <card_number> ? If that works, then it's just a matter of what your default soundcard is, and can easily be changed in /etc/asound.conf of ~/.asoundrc.

However, if alsaconf itself doesn't work, then does it print any more precise output? Then there's always the aspect of trying your soundcard at all, does it react to "cat /dev/urandom > /dev/dsp" ? If it doesn't it my be a problem with your autodetection tool (hwd or similar).

Re: Alsa problems after a system upgrade

i'm not quite sure what you mean, i'm still very new to all this

when i run alsaconf it all seems to work until the end when i get this message

Loading driver...
:: Saving ALSA Levels                                                    [DONE]

Setting default volumes...
amixer: Mixer attach default error: No such device

please note that i have to scroll up to see this.

when i try and run alsamixer i get the following error

alsamixer: function snd_ctl_open failed for default: No such device

Re: Alsa problems after a system upgrade

did you allow it to write the alias in modprobe.conf?
Also note to use sound for a regular user you must add them to the audio group otherwise you'll get messages like you last one.

Re: Alsa problems after a system upgrade

my user is in the audio group

and the modprobe.conf looks like this

#
# /etc/modprobe.conf (for v2.6 kernels)
#

# OSS Compatibility
install snd-pcm modprobe -i snd-pcm ; modprobe snd-pcm-oss ; true
install snd-seq modprobe -i snd-seq ; modprobe snd-seq-oss ; true

install nvidia modprobe -i nvidia ; /etc/udev/scripts/create-nvidia-nodes.sh ; $

Re: Alsa problems after a system upgrade

it's stated in udev readme, remove old entries from modprobe.conf, they cause problems, OSS and ALSA entries just remove them

Re: Alsa problems after a system upgrade

by commenting out the lines

install snd-pcm modprobe -i snd-pcm ; modprobe snd-pcm-oss ; true
install snd-seq modprobe -i snd-seq ; modprobe snd-seq-oss ; true 

alsamixer now works, i still haven't got any sound but i'll try and sort that myself before asking for more help

thanks to everyone who's helped

Mike

Re: Alsa problems after a system upgrade

usage of alsaconf is not really recommended until you have very old hardware that needs to be detected, the rest is handled by udev

It's not? I couldn't get my soundcard properly recognized, even with the correct modules loaded, before using alsaconf. Possibly that's just an evidence of my lack of knowledge in the matter.

maybe try disabling your onboard sound?

Re: Alsa problems after a system upgrade

@ toxic, well alsaconf is usefull for old ISA CARDS, newer ones should be fine loaded by udev anyway.
alsaconf can add stuff to modprobe.conf which mostly causes problems when upgrading to newer kernel versions.

Re: Alsa problems after a system upgrade

Sound can be a lot of fun in linux, for sure.  You shouldn't need alsaconf for an SBLive card - udev should handle it nicely.  You've already commented out those two lines (why are they still there?) in modprobe.conf.  You're on the right track.  As has been said, disable your onboard sound in BIOS - this will most likely clear the issue up right away.

Verify that your mixer isn't set to zero or muted - you can use alsamixer for this, or whatever the native mixer app for your desktop is (kmix for kde, gmix for gnome).  This used to be a common problem, but I think it's been resolved - still, check it out. 

Also, if you have a "Digital Out" option, but you are using analog out, you almost always want that option set to off.  I can't remember if this is even an option on SBLives, but it is on all Audigys that I've seen, and it causes people a lot of heartburn.

People praise soundblaster and linux, but honestly I've had a number of issues with the cards - not that they don't work, but they often don't work as expected.

Good luck!
